The transition function for the language L = {w|na(w) and nb(w) are both odd} is given by:
δ(q0, a)=q1 ; δ(q0, b)=q2
δ(q1, a)=q0 ; δ(q1, b)=q3
δ(q2, a)=q3 ; δ(q2, b)=q0
δ(q3, a)=q2 ; δ(q3, b)=q1
the initial and final states of the automata are: (A) q0 and q0 respectively (B) q0 and q1 respectively (C) q0 and q2 respectively (D) q0 and q3 respectively
